To all whom it may concern:

Be it known that GLEN .V. IR LAND, a citizen ofv the United States," residing at Miles City, in the county of Custer and State of Montana, has invented certain new and useful Improvements m a Welding, Brazing, and Tempering Compound, of which the following is "a specification. r

' My invention relates to a new composition of matter .in the form of a flux forusein welding, tempering and brazing. It is adapted for welding high and low carbon steels, irons of all kinds, the brazing of-cast iron or cast steel with brass or copper and the general welding of metal of the same or different kinds. i A

. My compound is particularly adapted for use in connection with welds made in blacksmiths fires. By its use,-the operation of welding high speed .steel and lowycarbon steel is rendered easyof accomplishmentf In welding with the acetylene"torch, the compound acts as a'flux for all metals suchas cast iron, brass, copper, steel, cast-steel,- bronze and aluminum.' Inthe use "of my fiux, the weld of the'se', metals will be found to be free from im urities and very ductile,

rendering the'wel easily machined. Furthermore-the use of my compound with the: acetylene torch results'in the formation of or dirt to come to the surface and'leayesjgno I havecarbonize the metal Iati the-weld nor to cause excessive oxidatio ith esult that the weld is strong and tou h; 3.,

My compound also-Q as nnportantfuse in connectionwith the tempermgnf steeland the restoring of burned steel to. its naturalstate. I find that'j-in thek-use of myco'm pound, the steel 'canbe'heated to a muchhigher degree than heretofore thought pos sible with the result th'atfjthereislfabetter absorption of the compound and a more of-1'1. fective tempering throughout.

In the forging and temperingofsteel for chisels and cutters, I take tool steel and heat. ,it to a high "degree, that is from 1400,,F. to 1800-13. and the compound, applied in m'ea diately upon withdrawal from the fi're. It is then forgedinto shape and subject to a' second heating. After 'withdraw'al'from "the fire an additional quantity of flux is'apphed to the heated portion and fit] is dippe'a di in;

to the high degree mentioned.

The flux and tempering compound of my invention, is composed of the following materials, the proportions being by weight;

Powdered borax, 85 parts; carbonate of --iron (commercial), 12 parts; bicarbonate of soda (commercial), 2 parts. These ingredients are thoroughly mixed 'andap lied as described.

I claim: 1. A welding and tempering fiux in the form of a dry mixture of powdered borax,

85 parts carbonate ofiron, 12 parts and bicarbonate of soda, 2 parts.

2. A new composition of matter for usein welding, brazing and tempering, consisting of powdered borax, 85 parts, commercial carbonate ofiron, 12 parts, commercial bicarbonate of soda, 2% parts.

In testimony whereof I have aflixed my signature.
